Intelligent kitchen waste processor control method and system

Abstract

The invention discloses an intelligent kitchen garbage processor control method and system, and the method comprises the steps: S1, executing a low-speed operation program, entering a no-load interval by default, and keeping a relay in a load partition recognition circuit in a closed state; s2, assigning Irate to the rated current of the motor; s3, after the operation of the motor is detected, synchronously reading a no-load current Ibus0 and a bus voltage Vbus0; s4, when the change of the current of the motor is detected, synchronously reading the loading current Ibus1 and the bus voltage Vbus1 of the motor, and calculating and judging whether the bus current variable quantity exceeds a first threshold multiple of a no-load bus current value or not; if yes, S5, judging that the bus enters a heavy load interval, otherwise, S6, switching to a light load partition processing mode, and calculating and judging whether the variation of the bus power exceeds a second threshold multiple of a no-load bus power value or not; if yes, S7, it is judged that a light load interval is entered; otherwise, S8, entering a no-load interval, and controlling the relay to turn into an open-circuit state; the first threshold multiple is greater than the second threshold multiple.

Description

technical field [0001] The invention relates to the technical field of motor control, and more specifically, to a control method and system for an intelligent kitchen waste processor. Background technique [0002] Due to the continuous advancement of urbanization and the general improvement of human life, the amount of garbage generated in this process is large and various. Only relying on landfill and natural decomposition for treatment, the separation of garbage is very slow and may take up a lot of waste. At the same time, it will also pollute the groundwater, air and other environments. Therefore, it is necessary to strengthen the manual treatment of garbage. [0003] Most of the existing garbage disposers use brushed motors, and some garbage disposers are equipped with motor controllers, but the motor controllers generally adopt the sensory control method with HALL sensors. Even if some of them use sensorless control methods without sensors, the control Poor performanc...

Problems solved by technology

However, the current characteristics of light loads such as water flow are equivalent to the no-load current level of the motor, which is prone to misjudgment, so that the speed cannot be switched normally and timely. When dealing with such or similar extreme loads, they need to be compatible In the case of operation, the existing sensorless control algorithm has defects, which cannot guarantee the normal switching of speed and the accuracy or even precision of control.
